Review: July 20, 2016Completion: June 9, 2016

Hello Greg, I just had to drop you a line to tell you how pleased we are with the Interlock Roofing System that was installed last week. I have to admit that as good as I was hoping it would look, it turned out to be so much better than I had even hoped. We couldn’t be prouder of how our house looks now; the new roof is visually stunning. We can now breathe a huge sigh of relief, knowing that we’ll never again have to go out into the yard and pick up the pieces of asphalt shingles that would blow off of the roof after a storm or a high wind day. To boot, the very day after the roof was completed, we had someone who identified himself only as “your nosy neighbor from 10 miles down the road,” who stopped, knocked on our door and started asking questions about the roof. He was shocked to hear that it was a metal roof. He thought that we had installed a slate roof! He was very interested to hear all the facts about the roof, and suddenly I became Interlock Roofing’s most avid salesman. I brought out your business card so that he could take a picture of it with his cell phone, and he said he’d be contacting you soon. I’ve also been talking about the roof with some of the guys at work who had seen the before and after pictures that I brought in, and I’m sure that you will be hearing from some of them in the future too. Now, as much as I couldn’t be happier with contacting you and doing business with you, I have to tell you that even you will have to take a back seat to the super awesome job of your installers, Jesse and his team. To say we were blown away by these guys would be the understatement of the century. They came in like a whirlwind and started doing their thing and made astounding progress in such a short period of time, it blew us away. Jesse himself is such a great face to have attached to your company. He is professional, knowledgeable, and so personable that we knew in an instant that we were in good hands with him and his team. All of his team members were that way, and honestly, the hardest working group of guys that you will ever witness. We expected it to take anywhere from 5 days to a week to get our whole roof done. These guys had it done in 2 days and a couple of hours, and they left no stone unturned in doing the A-1 job that was promised. They even fixed a couple of cosmetic items on our existing siding to boot! What a great bunch of guys. And let me reiterate one more time,…Interlock, as a company, should feel confident and proud to have Jesse and his team representing them. I’m positive you will never find a better team to install your product than them. Again, thank you for the product and the work that you’ve done. You now have not only a very satisfied customer in us, but you also have a couple of very enthusiastic ambassadors for Interlock Roofing Systems.

Review: June 17, 2017Completion: February 17, 2017

I have made, and continuously still make, numerous recommendations to family & friends to install a Interlock roof. And, I have produced pictures on demand that I stored on my smart phone. If possible, I would be appreciative if I could get the drone footage that Jesse had taken after the finishing of the installation. I believe it would be a great selling point coming from a true customer to help propel the Interlock name. There are just a couple areas on the roof that the installation crew could have touched-on during the installation, but overall the roof looks simply amazing. Quality certainly displays the professionalism the installers had put into their work. Since the installation of our new roof, we have received numerous compliments from many of our neighbors that walk around our subdivision, plus a handful of neighbors in the adjoining subdivisions. Many questions have been asked with many answers given. We are definitely happy with our new Interlock roof. We have NOT once questioned or second guessed our decision to install an Interlock roof. It is one of the best decisions we have ever made for re-investing in our home...Thank you, Interlock!

Review: June 8, 2008Completion: November 30, 2007

I never really thought I could be thrilled about a roof, but I have to tell you; our new Interlock roof is beautiful! It adds true elegance to our home. We know it adds value as well, and the fact that we will never need to re-roof again is a definite advantage. Everyone within our organization, from the initial phone contact to the installation crew, was courteous and pleasant to work with. The install went smoothly and the crew kept the site clean from beginning to end. Everybody we have shown our Interlock roof to has seemed quite impressed also. We would (and in fact have already done so) recommend Interlock Roofing to others.

Review: July 20, 2016Completion: November 13, 2008

Excellent roof! Looks good! The installers were courteous and professional. Put the tarp all around the house and kept the site very clean. I was impressed with their super service. They bent over backward to please us. The A-Team of Roofing! When it rains, it is NOT any louder, and we are in a wind zone, and shingles have not blown off, and we have had the roof since 2008. The snow slides off, too! And the salesman knows his product and explains it well. It will add value to the house. Unlike asphalt, that's like tar and paper, and doesn't hold up. The Interlock Lifetime Roof is super durable!d Greg Weber the salesman, knows his product and explains it well. It will add value to the house. Unlike asphalt, that’s like tar and paper and doesn’t hold up. The Interlock Lifetime Roof is super durable!

Review: May 17, 2017Completion: August 10, 2009

We purchased our roof in 2009 and as you can see from the pictures taken in May of 2017, our roof looks as new as the day we bought it. Here are the things we have noticed most about our Interlock Lifetime Roof over the last 8 years. It keeps our house much cooler in the summer than the asphalt roof we used to have. It really sheds snow, and the snow guards work great. We never need to use a snow rake. We love the durability and the curb appeal. Greg Weber our representative, who we were enthused to learn, is still with the company. When we saw him in 2009 he laid out all the variables in a professional way and our Interlock Roof has lived up to all of our expectations and promises he made. All companies promise results, service, and quality. Interlock delivers.

Review: May 16, 2017Completion: July 31, 2008

The installation was super smooth. Every installer was courteous and professional. We get lots of compliments, and people stop by all the time to admire it. One of the biggest misconceptions about metal roofing is people think it’s loud. Our Interlock roof is very silent. The only way I know if it’s raining is if I look out a window. Also, the snow just slides off. We are also in a wind tunnel area, and we have never lost an Interlock shingle, and we have had the roof for many years. We were so pleased with our Interlock roof that we put the same roof on our lake home in northern Wisconsin. We get a lot more snow up there and the Interlock’s snow-shedding performance capabilities are second to none on that roof, too!

★★★★★
Review: April 10, 2017Completion: March 17, 2015

I love the roof! It looks great, and the squirrels that we’re crawling all over my old asphalt roof slide right off it. The snow slides off, too. I hope to get some $500 referrals. The crew was terrific, hardworking, courteous, polite, and clean.

Review: April 23, 2009Completion: May 5, 2008

Drip, drip, drip. This is not a sound you want to hear at 3:30 am… in bed… coming from your attic… in the dead of winter. A quick peek in the attic confirmed my worst fears, the ice dam on the roof was allowing melted water to seep through the crappy asphalt shingles and into the house. We called a local contractor and had the ice dam removed, but this didn’t fix the underlying problem that our current roof was cheap and damaged. My wife and I moved into a beautiful three-story brick Tudor on Madison’s near west side in the fall of 06′. It was perfect in that it had been beautifully remodeled with gorgeous woodwork, marble, and stunning attention to detail, with the exception of the roof. We had decided that, barring any unforeseen circumstances, this was the house we were going to stay in until retirement, so why not invest in a metal roof. After a couple of weeks of research and interviewing, we settled on Interlock. Part of the choice was made on the quality of the product, and part was made on the salesmanship of the rep, Chuck. Work started and except for some problems with the weather, things progressed smoothly. We were especially impressed with the steps the crew took in regard to safety, and our stay-at-home neighbor told us about how exciting the crew was, “you’re definitely getting your money's worth,” was her exact quote. At the end of the job, the crew even emptied all the trash we had pulled out of the attic for us. Now that’s service! After everything is said and done, we’ve been able to cap off our gorgeous house with an equally gorgeous roof.

Review: April 16, 2026Completion: February 20, 2009

I had Interlock put on a beautiful red slate roof 17 years ago.The roof still looks beautiful. 5 years ago, I had them also re-roof my garage with the same type of slate. The roofs look gorgeous and I have no maintenance whatsoever.I get complements all the time. The guy whom I contracted with was named "Tim' but has since died. He was a really nice guy. Back in 2009, the roof was much cheaper. ( I actually paid more for the garage 5 years ago!) I am extremely happy with the roofs. The guys did a wonderful job, replacing rotted boards where necessary. They also told me about very cheap gutters I could buy at Menards instead of those ridiculously - priced "special" gutter systems. I bought them and they placed them on my buildings.This home will go to my daughter one day; I do not want her to have to lift a finger. Note that I had an asphalt roof previously. It lasted only 12 years. The shingles curled up under the sun and cracked. They looked terrible. I can honestly say that these metals roofs by Interlock are very much worth what you pay for them. They will last a lifetime with almost no maintenance. Instead of replacing a roof every 15 years and paying lots for asphalt or fiberglass, their metal roofs last very long and you will never have to re- roof again.

Review: May 16, 2017Completion: September 24, 2014

Dear Interlock Lifetime Roofing Systems: We purchased our Interlock Lifetime Roof in June 2014. We are very happy with the look, durability of the material, and finish. After a snowfall, the heat of the sun will warm the roof and allow the snow to shed from the roof. We have a great sense of security, knowing it can withstand higher winds than conventional asphalt. In fact, our neighbors lost many shingles in the last major wind storm, and our Interlock roof proved to be the high wind resistance product it is with all shingles intact. We love the fact it’s more reliable and has peace of mind knowing it has lots of longevity and will look brand new not only now but down the road. We also received a discount on our homeowner’s insurance. Overall, we were very satisfied with our sales representative Greg Weber, the company, the service, and the product.

★★★★★
Review: May 10, 2017Completion: March 20, 2017

In March 2017 we had an Interlock Lifetime Roof installed. Greg Weber, the salesman, was not pushy. We were very impressed with his salesmanship and the product. He also offered to have the Interlock product put on our wishing well in the front yard. That was something we really appreciated. The clean-up was excellent! Many neighbors and people who " data-wpil-keyword-link="linked">walk by the house have noticed the roof and asked a lot of questions. We have gotten lots of compliments!

★★★★★
Review: April 10, 2017Completion: February 23, 2017

The Interlock crew was able to take some extra time to coordinate with another contractor for solar installation. As a result, the final the result looks great and very functional. The materials used are very high quality, and they worked efficiently and cleaned up when finished.

Metal Roofing FAQs for Homeowners in Carthage

The following metal roofing FAQs are designed specifically for homeowners in Carthage, Wisconsin. Whether you are building a new home or replacing an existing roof, understanding how roofing materials perform in local weather conditions is essential. From wind and storm protection to fire resistance, hail impact, snow loads, and coastal moisture exposure, Interlock’s Lifetime Aluminum Roofing System is engineered to provide long-term durability, energy efficiency, and peace of mind in Carthage.

How does a metal roof handle Carthage's annual snowfall and freeze-thaw cycles?

Interlock's aluminum panels shed snow and ice more effectively than asphalt because the smooth, hard surface prevents buildup and the four-way interlocking seams create a seamless barrier. Carthage averages about 98 cm of snow yearly and experiences roughly 81 freeze-thaw days per year—conditions that cause asphalt to crack and curl. Aluminum's oxide layer doesn't degrade in this cycling, and the panels' light weight (Slate installs at just 0.41 lb/sq ft) means no structural strain from snow loads. The standing-seam and shake profiles naturally direct meltwater away, reducing ice-dam formation that plagues heavier roofs.

Why won't my metal roof rust in Wisconsin's climate?

Interlock panels are made from roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209), which contains no iron—the element that rusts. Instead, aluminum develops a thin oxide layer that actually protects the metal underneath and self-heals when scratched. Steel roofs rust; aluminum cannot. With Carthage's roughly 760 mm of annual rainfall and occasional wind gusts reaching 97 km/h that can scrape surfaces, this is a real advantage. The Alunar 70% PVDF fluorocarbon coating applied to both panel sides adds a 30-year fade and chalk warranty (ASTM D4214), so even the finish stays protected for decades.

Will freeze-thaw damage affect an aluminum metal roof over 25+ years?

No. Aluminum expands and contracts with temperature swings, but doesn't crack, curl, or split like asphalt, wood, or concrete tile do under repeated freeze-thaw stress. Carthage endures about 81 freeze-thaw days annually—a significant mechanical stress—yet aluminum's crystalline structure accommodates this movement without degradation. The Guardian warranty explicitly covers splitting and cracking for the original owner for life, then transfers for 50 years to the next owner. Asphalt shingles typically fail within 15–20 years in this climate; Interlock's proven track record since 1998 in similar and harsher regions (Antarctic research stations, coastal salt air) shows the material simply outlasts the conditions.

Can my existing roof structure handle a metal roof, or do I need reinforcement?

In almost all cases, no reinforcement is needed. The Mediterranean Tile profile, which replicates the heaviest traditional roofing material, installs at just 0.59 lb/sq ft—about 96% lighter than actual concrete or clay tile. Your home's framing was engineered to carry asphalt shingles (typically 2–4 lb/sq ft), so aluminum is substantially lighter. This also means Interlock can install directly over most existing roofs, saving thousands in removal and disposal costs. Carthage's average snow load (tied to 98 cm annual snowfall) is well within what your current structure already supports; aluminum simply adds negligible weight while providing superior durability than what's currently above your head.

Will my homeowner's insurance cover hail damage to a metal roof?

Yes, and some insurers offer discounts. Interlock panels carry a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. This non-combustible aluminum construction often qualifies for lower premiums than asphalt (which dents easily and deteriorates faster in severe weather). Carthage's wind gusts reach 97 km/h, and hail can accompany severe storms. Contact your insurer with the UL 2218 Class 4 rating; many carriers recognize this as equivalent to or superior to traditional roofing and may adjust your rate downward. The durability alone—versus repeated asphalt claims—makes you a lower-risk policyholder.

How does Interlock's metal roof perform in Wisconsin wind and storms?

Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Carthage's typical gusts reach 97 km/h, well below this rating, meaning your roof will remain secure through normal storms and even severe weather events. The interlocking seams—not nails or screws alone—distribute wind load across the entire panel assembly, preventing the lifting and peeling that weakens asphalt shingles. Installation follows the ICC-ES ESR-1790 evaluation (reissued 2025), the national standard for metal roofing over wood-frame homes. This engineering-backed approach, combined with the panels' lightweight aluminum construction, creates a roof that actually becomes more secure over time as the interlocks settle.

Is metal roofing more cost-effective than asphalt over the long term?

A metal roof is your last roof. While Interlock typically costs 2–3 times more than asphalt upfront, you'll install asphalt 3–4 times in a 50-year span (each cycle runs $8,000–15,000 in removal, disposal, and labor). Interlock's lifetime limited warranty for the original owner—then 50 years transferable—means one installation covers your ownership and adds value for the next owner. No tear-offs, no landfill fees, no mid-season failures during Wisconsin's 81 freeze-thaw days. Over 50 years, you'll spend roughly half what asphalt costs, and your home avoids the labor disruptions and hidden damage (rot, mold) that come with repeated roof removal. The Guardian warranty's non-prorated coverage means you're protected against every failure mode—rusting, rotting, cracking—that asphalt and wood can't avoid.

What exactly does Interlock's lifetime warranty cover, and for how long?

The Guardian warranty is a lifetime limited, non-prorated material warranty for the original owner covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's one-time transferable, giving the next owner 50 years of coverage from completion. This means you're protected for life; the next homebuyer gets half a century more. No other roofing material offers this combination: asphalt shingles carry 20–25-year warranties but are prorated (you pay more in year 10); slate and tile rarely transfer. Interlock's 95% recyclability also means when the roof eventually outlives the structure, the material goes back to aluminum mills, not a landfill—a 27-year commitment to sustainability built into the guarantee.

How much maintenance does an aluminum metal roof really need?

Almost none compared to asphalt, wood, or tile. You don't clean gutters of deteriorating shingle fragments; aluminum sheds debris cleanly. No moss or algae growth on the smooth surface. No wood rot, splitting, or replacement of individual shakes (cedar requires re-staining every 10 years). No cracking from Carthage's 81 annual freeze-thaw cycles. Asphalt degrades under UV and the region's 3,073 sunshine hours per year; Interlock's Alunar 70% PVDF coating is warranted 30 years against fade and chalking. A simple annual inspection and gutter cleaning—which you'd do anyway—is sufficient. CALGreen verification confirms reduced maintenance burden, freeing you from the constant upkeep that masonry and wood roofs demand in Wisconsin's wet, cycling climate.

Who installs Interlock Metal Roofing in Carthage, and what's their experience?

Interlock Metal Roofing has served the Kenosha County region since 2001, bringing over two decades of installation expertise to Carthage and surrounding communities. The company manufactures panels in Delta, BC, and has deployed them from coastal salt-air homes to an Antarctic research station—so your roof benefits from installation knowledge across extreme climates. Local service means your installer understands Carthage's specific snow loads (about 98 cm yearly), freeze-thaw stress (81 days), and wind patterns (gusts to 97 km/h). They're familiar with Wisconsin building codes, can navigate your homeowner's association if needed, and stand behind every job under the ICC-ES ESR-1790 standard. Choosing a local, long-established installer ensures accountability, faster service calls, and someone who'll remember your roof 10 years from now.

Is a metal roof a good choice for Carthage’s climate?

Yes. Carthage averages about 98 cm of snow, 760 mm of rain, roughly 81 freeze–thaw days a year, with peak wind gusts near 97 km/h. Interlock® aluminum roofing is wind-rated to 193+ km/h (120 mph), UL 2218 Class 4 impact-rated and Class A fire-rated, and its four-way interlocking panels shed snow and resist ice dams and freeze–thaw cracking — all backed by a lifetime limited, transferable warranty.
